But I also think it's some kind of dead end. Not only does eg. BeOS not support that Cirrus card (last time I tried BeOS inside Qemu, it complained that the Cirrus card is too old :-) . Also I'm not sure whether the Cirrus card will ever be fast enough for that. Do "real" Cirrus 5446 cards offer hardware video acceleration? And do they offer 2d acceleration that can be used by DirectDraw? They certainly don't have 3d support, so if Qemu should have fast 3d graphics one day, it will certainly not work with the current graphics emulation. So, I think we shouldn't dismiss the possibility of a special Qemu graphics card (and driver). The Cirrus card (and -std-vga) should still be available for those systems where the Qemu graphics driver is not available, while the users who run a wide-spread, recent system as guest can have faster graphics. Just my two cents, Oliver Gerlich -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFDZLY+TFOM6DcNJ6cRAoCxAJ9yAC8Th6DfuXnPQJ1m7mn85RvPoQCeKj6D 2XyhMcUQQ+lsy5bQn1IOuHY= =LoQ7 -----END PGP SIGNATURE-----
